To a/ZZ whom t may concern:

Be it known that lI, CHARLES PREVET, of the city of Paris, France, have invented an Improved Hose-Coupling, of which the following is a full, clear, and exact description.

This invention relates to a hose-coupling for connecting one lengthof rubber hose to another or to a draw-off cock. A,

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is an external view, and Fig. 2 a longitudinal section, of the hose-coupling. Fig. 3 represents the coupling attached to al draw-off cock.

The same letters of reference denote like parts in all the figures.

The coupling comprises an expansible spigot formed of a screw-threaded tubular stem a', provided with a head d and garnished with a sleeve l), of rubber, provided with a fia-nge b', the sleeve being confined between the head ce and a cap c, recessed to receive the rubber flange b', the cap being slipped on the stern and pressed toward the head CL by a nut e, screwing on the stein a and acting, through a distance-collar d, so as by the pressure to compress the tubular rubber sleeve b longitudinally and expand it dianietiically. The

lower threaded end is screwed into the bore of the rubber hose g, which may be secured by a wire binding, if necessary, a washer f being interposed between the nut e and the hose g.

A hosecoupling consisting of an expansible spigot formed of a inushroo1n-headed tubular screw-threaded stem communicating with the hose attached thereto, a flanged india-rubber sleeve b b confined between the head a and a cap c loose on the stem and recessed to receive the flange h and a nut e screwing on saidstem and acting to compress the rubber sleeve longitudinally and expand it diametrically so as to cause it to t tightly in the-bore of the nozzle or socket of the cock or pipe to which it is to be connected and also compress its flange h against the end of the nozzle or socket substantially as specified.
